| Summary |
Stochastic Resonance (SR) is considered as a noise enhanced
phenomenon, that a response of a nonlinear system is improved by
noise. In previous studies, an application of SR for wireless
communication has been discussed and an SR receiver, the receiver that
demodulate a received signal by SR, was proposed. However, these studies
have used a basic modulation signal and have not focused on a signal
that transmit information by multi-level amplitude. In this paper, we
consider an SR receiver for 4-pulse amplitude modulation (4-PAM) signals. By applying SR, it can
demodulate 4-PAM signals by a 1-bit
resolution device. We show the system model of the receiver, evaluate
its performance by simulation, and show its availability. |
